The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

“content for output.” Id. at 89. We determine, however, that Petitioner’s argument under Step 2A Prong One that claim 1 is directed to the “obtaining content for output” is not substantially different from the Examiner’s determination that claims 1‒20 recite “collecting information, analyzing it, and displaying certain results of the collection and analysis.” Compare Pet. 37–88 (citing e.g. Electric Power), with Ex. 2001, 193–194 (also citing Electric Power). In both cases, the argument is the same or substantially the same, i.e., that similarly identified subject matter of the claim is obtaining (collecting) data and displaying (outputting) it. Nevertheless, as to Step 2A Prong Two, we determine that the claims at issue in the ’096 prosecution differ in material ways from the ’903 patent claims at issue in this PGR. Specifically, the ’096 patent claims recite a touchscreen interface not recited in the ’903 patent claims. Additionally, the ’903 claims focus on the “output device” as performing the patented steps but in the ’096 prosecution history the “‘information apparatus performs the patented steps and “is integral to the claims” (as the Applicant argued). See Ex. 2008 [comparison of ’096 prosecution claims and ’903 claims]; Ex. 2001, 150; see also Pet. 89 (“the claims at issue in the ’067 application were different than the claims of the ’903 patent addressed here.”). rejection and arguments in the ’096 prosecution history turns on whether the claims in this PGR recite different elements that must be determined to integrate the judicial exception into a practical application (i.e., Prong Two of Step 2A). Petitioner argues that an essential element different than the ’096 claims, i.e. the output device, does not integrate the judicial exception into a practical application because the claims do not amount to an improvement to computer functionality. Pet. 37–72. We find this a close case. Nevertheless, due to the differences in the claims, we determine that the Examiner’s withdrawal of the § 101 rejection in light of the applicant’s arguments regarding the claim being directed to a specific technical solution is not substantially the same argument that Petitioner’s presents in the Petition as to Prong Two of Step 2A.” slip op. at 22

“in the art at the time of the invention] would have understood that an output system/device could be (or include) an information apparatus. Prelim. Resp. 24. We determine that Patent Owner’s argument has a logical flaw––i.e., the fact that a particular device could be used alternately as an information apparatus or an output device does not necessarily mean that it was known by one of ordinary skill in the art to use a combined information apparatus/output device and have the new combined device perform all the additional functions required by the claims. “The knowledge of ordinary artisans may be used to inform what is actually in the specification, but not to teach limitations that are not in the specification, even if those limitations would be rendered obvious by the disclosure in the specification.” Rivera v. Int’l Trade Comm’n, 857 F.3d 1315, 1322 (Fed. Cir. 2017) (“Rivera”). “The question is not whether a claimed invention is an obvious variant of that which is disclosed in the specification . . . . It extends only to that which is 1997). Patent Owner has not pointed to any disclosure in the ’413 application teaching that an “output device” can perform the functions of the “information apparatus” including its interactions with the “output device.” For example, claim 1 recites “wirelessly receiving, by the output system . . . output data from at least one server of the one or more servers over the Internet.” Ex. 1001, 37:28–32. At this stage, we find sufficiently persuasive Petitioner’s argument, which we discuss above, that the only written description support for an “output device” that performs the claimed functions by accessing the Internet provided by Patent Owner is not an “output device” but an “information apparatus.” Prelim.

Dr. Miller provides relevant opinions on a number of issues, particularly including how a person of ordinary skill in the art would understand certain terms in light of the Specification, that are helpful to us as the trier of fact. “There is no more certain test for determining when experts may be used than the common sense inquiry whether the untrained layman would be qualified to determine intelligently and to the best possible degree the particular issue without enlightenment from those having a specialized understanding of the subject involved in the dispute.” Ladd, Expert Testimony, 5 Vand. L. Rev. 414, 418 (1952).” slip op. at 14

“shared “in real time utilizing a second network protocol . . . ,” and dependent claim 59 recites that information is processed “to create, in real-time, messages in at least two other message formats . . . .” Petitioner argues that the Specification of the ’843 patent expressly defines “real-time”: “In the context of the present description, real-time may include any response time that may be measured in milli- or microseconds, and/or is less than 1 second.” Ex. 1001, col. 3, ll. 35–38. Accordingly, Petitioner proposes that “‘real-time’ should be construed as responses that occur in less than one second.” Pet. 13. Patent Owner contends that the definition from the Specification should be adopted. PO Resp. 15. We construe “real-time” as Petitioner proposes, i.e., as including responses that occur in less than one second. The first part of the quote cited above provided in the Specification (“may be measured in milli- or microseconds”) is not limiting because any response time, no matter how large or small, may be measured in milli- or microseconds.” slip op. at 16

“been reached in association with the storage request.” Petitioner proposes that “threshold” be construed consistent with a dictionary definition it provides, as a “value above which something is true or will take place and below which it is not or will not.” Pet. 13–14 (citing Ex. 1016, 5). Observing that the Specification of the ’843 patent uses “threshold” in the context of an elapsed time, Petitioner further proposes that this construction “include the maximum value (i.e., time-out) of a timer.” Id. (citing Ex. 1001, col. 8, ll. 21–25, col. 8, ll. 47–51). We agree, and accordingly construe “threshold” as Petitioner proposes.3 3. “heterogeneous networks” Dependent claim 55 recites that the “apparatus is operable such that the first network and the second network are heterogeneous networks.” The Specification of the ’843 patent defines “heterogeneous networks”: “In the context of the present description, heterogeneous networks may refer to any different communication networks with at least one aspect that is different.” Ex. 1001, col. 7, ll. 26–29. In light of this explicit definition, for purposes of this Decision, we construe “heterogeneous networks” as Petitioner proposes, i.e., as “networks having at least one aspect that is different.” Pet. 14 (citing 3 Patent Owner advocates for the same construction advanced by Petitioner, but omits inclusion of the maximum value of a timer. PO Resp. 15. Although Patent Owner asserts that the construction is otherwise “the definition provided by the ‘843 Patent,” it does not cite to the ’843 patent to support its assertion, and we are unable to identify such a definition in the patent. Nevertheless, we agree with Petitioner that any distinction between the constructions is not material to any grounds. See Reply 6.” slip op. at 16
